Zal Yanovsky, 57, whose distinctive guitar playing and ebullient personality helped make the Lovin' Spoonful one of the most popular rock groups of the late 1960s, died of a heart attack Friday at his home outside Kingston, Ontario.

One of the biggest North American rock bands when the Beatles and other British acts dominated the pop charts, Lovin' Spoonful had 10 singles in the Billboard Top 40 between 1965 and 1967. Their first seven -- beginning with "Do You Believe in Magic?" -- all reached the Top 10, and "Summer in the City" reached No. 1 in 1966.

By the time the group released what would be its last Top 40 record, "She Is Still a Mystery," Mr. Yanovsky had left. Not long after that, the Toronto native left the music business entirely and began a successful second career as a restaurateur in Canada.

Hugh Clarke Tuttle, 81, patriarch of a farm in Dover, N.H., honored as America's oldest continuously run family business, died there Saturday after a long period of failing health.

Part of the 10th generation of Tuttles to manage the farm on Dover Point Road near Maine, Mr. Tuttle was credited with transforming it into a modern family corporation. As surrounding farms succumbed to debt, a lack of interest from succeeding generations, or pressure from real estate speculators, the Tuttle Farm adapted and thrived.

Today, it is a 240-acre, fully computerized operation that features a 9,000-square-foot food emporium serving 1,000 customers a day. More a retailer than a producer, Tuttle Farm now grows less than 10 percent of all the goods it sells.

The story of the Tuttle Farm began in 1632. John Tuttle, an apprentice barrel-maker from Bristol, England, and his family were shipwrecked on the Angel Gabriel off the Maine coast. The family survived the wreck but lost almost everything.

With little more than the clothes on their backs and a deed from King Charles I to Dover Point land, they walked several miles and carved out a farm on 30 acres amid the towering white pines.

The Tuttles passed the family farm down from youngest son to youngest son -- as is the practice of their Quaker religion. During the early 1800s, the farm was a stopping point on the underground railroad for fugitive slaves.
